IT professionals believe that assessing the potential harm caused by data breaches is more useful to mitigating the effects of such incidents than notifying affected individuals, according to a survey published on the day the EU proposed a 24-hour deadline for data breach disclosures.

Entitled “Aftermath of a Data Breach,” the study was sponsored by information services company Experian and was conducted by the Ponemon Institute, which surveyed 584 experienced IT professionals working for companies that suffered a data breach involving consumer records during the past 24 months.

The questions asked by the Ponemon Institute tried to establish the circumstances leading to the data breach, the company’s response and the incident’s impact on the affected organisation’s data protection practices.

One of the study’s most interesting conclusions was that while notifying victims and regulators are the most common steps taken by companies in the aftermath of a data breach, IT professionals don’t view them as the most important actions for reducing the negative consequences of such incidents.

Only 6%of survey participants said that victim notification is helpful for reducing the impact of a breach, a significant change of opinion compared to 2007 when 54% of IT professionals chose it as an important mitigation step.

Retaining outside legal counsel, carefully assessing the harm to victims and hiring forensic experts to investigate the breach were viewed as the most valuable actions a company can take in the aftermath of a breach by approximately half of respondents.

By comparison, contracting computer forensic experts was considered important by only 5% of survey participants in 2007. This suggests that IT professionals today are much more interested in learning how a breach happened before taking action.

Legislators in both the U.S. and the European Union are pushing for legislation that would require companies to alert victims about data breaches in a more timely and uniform manner.

The European Commission proposed significant changes to the E.U.’s data protection laws Wednesday that include a 24-hour deadline for companies to report data breaches. While the proposal was largely welcomed by consumer protection groups, it attracted criticism from the U.S. Department of Commerce and business associations, which described the deadline as too short.

The Aftermath of a Data Breach survey also revealed that, despite making improvements to their data breach response practices, companies still have a long way to go as far as prevention is concerned. Only half of respondents believed that their companies made the best possible effort to protect customer and consumer information in advance of a data breach.

Negligent staff, disgruntled employees and third-party contractors remain the primary source of data breaches. Despite the large wave of cyberattacks that targeted companies last year, only 7% of respondents named such attacks as the cause for a data breach in their organisation.

According to the study, companies continue to avoid offering free credit monitoring or identity protection services to data breach victims, and when such services do get offered, they rarely exceed periods of one year.

Nearly half of respondents said that their companies suffered data breaches that involved log-in credentials and credit card or bank payment information. 60% of them said that the data was not encrypted, while 16% were unsure.
